The CURT 51343 Quick Plug brake controller harness offers a seamless, professional installation solution for your towing setup. Designed for select Cadillac, Chevrolet, and GMC vehicles, this adapter eliminates the need for manual wire cutting or splicing, allowing you to connect your trailer brake controller directly to your vehicle's factory socket.

Product Description

The CURT 51343 is a vehicle-specific wiring harness that bridges the gap between your truck’s electrical system and your trailer brake controller.

Whether you are replacing an existing unit or installing a brand-new controller for the first time, this harness provides a "plug-and-play" experience.

A protective slit loom sleeve is included to prevent abrasion and crushing, ensuring the longevity of your wiring.
